  • Until recently, the gene-editing tool CRISPR has only been able to make changes within single genes.
  • The new tools allow scientists to cut and splice larger chunks of genetic material.
  • The findings will likely have major implications for a variety of research fields, and also allow researchers to create synthetic species that can produce molecules not made by natural organisms.
